Peristalsis is a series of wave-like muscle contractions that move food, liquid and waste through the digestive tract, from the esophagus to the intestines. This peristaltic movement is automatic and controlled by the nervous system. When it slows down or becomes irregular, constipation or diarrhea can follow.
What is peristalsis?
Intestinal peristalsis is a wave-like contraction of the smooth muscles of the intestinal walls, which ensure the movement of food masses and liquids through the digestive tract. This process is automatic and controlled by the nervous system. These contractions begin in the esophagus and continue in the stomach and intestines, helping to mix food with digestive enzymes and promote its absorption.
How peristalsis works step by step
- Esophagus: waves of contraction push food toward the stomach.
- Stomach: food is mixed with digestive enzymes.
- Small intestine: contractions move the contents onward.
- Large intestine: contractions move the remaining waste toward the exit.
What can disrupt peristalsis?
Normally, intestinal peristalsis occurs regularly and ensures a normal digestive process. However, various factors such as stress, poor diet, sedentary lifestyle or diseases can disrupt peristalsis, leading to constipation or diarrhea.
Supporting healthy peristalsis
Intestinal preparations, supplements, or lifestyle changes can help restore normal peristalsis.
Ensuring healthy peristalsis is an important prerequisite for the proper functioning of the gastrointestinal tract and the overall health of the body, so it is important to maintain a balance between activity, healthy eating and stress. If digestive problems persist, consult a doctor.
Frequently asked questions

Where does peristalsis occur?
It begins in the esophagus and continues through the stomach and intestines.
What happens when peristalsis slows down?
Disrupted peristalsis can cause constipation or diarrhea. If digestive problems persist, consult a doctor.
What affects peristalsis?
